Looks good. could you use a bigger tube and put a wad between powder and shot and keep in just one tube?

There are lots of different vials on Amazon. I found some that I use for weighed charges for long-range rifle shooting. Some of them can have a little bit of static electricity problems that keeps some of the powder from dropping but they get better after a time. Wiping with an anti-static rag or clothes dryer additive may help as well.
